Changing bounds of imageView of UITableViewCell

I have a custom UITableViewController, and within I am dynamically styling a UITableViewCell with style UITableViewCellStyleSubtitle. All is good, except that when a cell is re-used, its imageView property does not respect my contentMode or clipsToBounds settings. Ideally, I would prefer the content to adhere to the default size/shape (which I believe is 40×40 square).

There are other posts (links below) that suggest subclassing UITableViewCell, or re-sizing your images to fit exactly, but both these feel like workarounds and (imho) would overly-complicate my code given that I am already pulling small (non-square) images.

Suggests subclassing UITableViewCell: Changing bounds of imageView of UITableViewCell

Suggests resizing all images: UITableViewCell's imageView fit to 40×40

Example code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *kCellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellIdentifier];
    if (!cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:kCellIdentifier];
    }

    NSString *mainText = @"mainText";
    NSString *subtitle = @"subText";

    [[cell textLabel] setText:mainText];
    [[cell detailTextLabel] setText:subtitle];

    // get album cover
    UIImage *imageForCell = [album objectForKey:@"coverImage"];

    // this is the broken part - 
    // it works upon first load, but it is NOT applied when a cell is re-used/dequeued..
    // instead, the image is displayed un-scaled and un-square
    [[cell imageView] setAutoresizingMask:UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth];
    [[cell imageView] setContentMode:UIViewContentModeScaleAspectFill];
    [[cell imageView] setClipsToBounds:YES];

    if (imageForCell) {

        [[cell imageView] setImage:imageForCell];

    } else {

        /* code to retrieve custom image */
    }


    return cell;
}

What gives? Is there a bug in UITableViewCell? Or is this for some reason by design?

Answer 1

I’m pretty sure Apple claims ownership of textLabel, detailTextLabel, and imageView with respect to layout, so I don’t think you can call this a defect.

-tableView:willDisplayCell:forRowAtIndexPath: is an API specifically for formatting the layout of a cell. You should have better luck making formatting changes there.

Didn’t work despite what the doc implied.
